The volume of a sphere is 36π cubic feet. what is the radius of the sphere? (v = 4 3 πr3)

radius = 3 feet

rearrange the formula making r the subject

πr³ = V ( multiply both sides by 3 to eliminate fraction )

4πr³ = 3V ( divide both sides by 4π )

r³ = = ( 3 × 36π ) / 4π = 3 × 9 = 27

take the cube root of both sides

r = = 3

the answe i =−n+5

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
